Xi'an Kefeng's High density tungsten alloys provide a unique combination of density, mechanical strength, machinability, corrosion resistance.
These refractory metal materials provide remarkable advantages when compared to traditional high density materials like lead or uranium.
Super high strength, consistent durability and long-lasting value, our high density tungsten heavy alloys are the perfect choice for radiation
shielding, weights and counterbalances, boring bars and grinding quills, crankshaft balancing, rotating inertia members, ordnance components,
and high-temperature tooling applications.
W-Ni-Fe alloys and W-Ni-Cu alloys (with tungsten content of 92.5%~97%) are regular tungsten heavy alloys with high density. We offer a variety of high density alloys, available in bars, plates, sheets, foil, and rods. We also have extensive machining capabilities, allowing us to provide weights in standard sizes or custom products finished to your required specifications. We also provide tungsten lanthanum alloy products in shaped and machined forms.

Kefeng tungsten Heavy Alloy Ring has excellent strength and ductility. We offer a variety of alloy compositions with different densities and mechanical strengths. We produce a variety of heavy metal products: W-Ni-Fe alloy, W-Ni-Cu alloy, W-Ni-Mo alloy.
This product is a tungsten alloy with a tungsten more than 90% refractory metal which have two-phase composites consisting of W-Ni-Fe or W-Ni-Cu to ensure a high density material, which the density ranges from 16.85 to 18.85g/cc, shapes varies from rod, ball, cylinder, block, ring etc. and are usually applied in the fields of military and defense, aerospace, medical and other Hi-tech industries.
Characteristics and features
The heavy tungsten alloy material possess the high temperature resistance, high impact resistance and crack, shock and corrosion resistance, also the highest melting point of all metals and suitable for very high-temperature applications. It is also characterized by a uniquely low coefficient of thermal expansion and a very high level of dimensional stability.
- High temperature resistance
- High impact and crack resistance
- Shock and corrosion resistance
- High absorption capacity against X-rays and gamma
- Good modulus of elasticity and high hardness
Application
All the characteristics of the tungsten heavy alloy rings make it useful in many industries, including military equipment, machinery manufacturing, aircraft parts, medical treatment, tungsten alloy counterweights, and tungsten alloy accessories.
- For commercial : sealed cap for transistors sealing welder, contactor materials for high voltage switches and electrodes for spark processing and more
- For military industry: penetrating projectiles, counterweights for military defense, projectiles in the missile weapons, armor piercing ammunition, prefabricated fragments
